ABSTRACT
A recent meta-analysis of 28 investigating the effect of exercise programmes on children’s cardiorespiratory fitness, indicated that aerobic training may only induce a small to moderate increase in cardiorespiratory fitness (Payne and Morrow, 1993). Few if any of these studies have objectively reported the intensity of the training programme. To increase cardiorespiratory fitness, Morrow and Freedson (1994) have recommended an intensity of 75% of maximum heart rate reserve, for twenty minutes, three times a week. A dearth of data on cardiorespiratory training in children makes a definitive prediction of a dose-response for increasing fitness impossible.
